# USB 2.0 vs USB 2.0 OTG

I am looking for some microcontrollers with USB capabilities and some are said to have USB 2.0 HS Host/Device with PHY others say USB 2.0 HS OTG Host/Device with PHY.

I am not a specialist in the USB specifications, so I wonder, choosing a OTG part will have any set backs or limitations?

I am expecting OTG parts to behave just as regular USB parts do, so if I program my part to act as host, and I connect it with a regular USB 2.0 device, they will connect as usual.

• What USB capabilities you require.....do you intend to connect it to PC to do something....or do u want some other USB device like USB drives to be connected to this and accessed......?Based on capabilities/application you can select host or device/// Sep 17, 2014 at 6:37
